T allwhom it may concern.-

Be it known that I, JOHN W. FRI S, of Winston Salem, Forsyth county,State of North Carolina, have invented an 1m provernent in Machines forTreating Yarn, of which the following is a specification.

My invention has reference to machines for treating yarn; and itconsists of certain improvements which are fully set forth in thefollowing specification and shown in the accompanying drawings, whichform a part thereof.

The object of my invention is to provide a construction ofmachine whichshall occupy small space and have capacity for successive immersions andrepeated squeezing during the treatment to insure full and uniformimpregnation of the dye or other liquor preliminary to the subsequentdrying operations with or without steaming.

My invention is especially useful in dyeing yarns with indigo,-which issoluble in alkaline solutions and which requires repeated clippings andsqueezings to secure the proper body of coloring-matter. In thesubsequent treatment the soluble indigo is oxidized by exposure to theatmosphere and rendered insoluble by loss of a portion of its hydrogen.

My invention comprehends a vat provided above the liquid-level with arotating cylindrical roller, and below the liquid-level within the Vat aseries of grooved wheels so journaledupon a transverse shaft as torevolve in parallel vertical planes oblique to the cylindrical roller,whereby the yarn in passing alternately about the roller and groovedwheels will advance from one end of the vat toward the other end and atthe same time be repeatedly dipped in or treated to the'dye liquor inthe vat.

My improvements also include, in combination with the above orequivalent means for treating the yarn, an elastic pressure-rollerresting upon the cylindrical roller and adapted to squeeze the yarn asit passes about said cylindrical roller and suitablyrotated so as toremove all retarding friction upon the yarn. My invention also embodiesdetails of construction which,together with the above specifiedfeatures, will be better understood by ref erence to the drawings, inwhich Figure 1 is a sectional side elevation of a dyeing-machineembodying my invention on line-w m of Fig. 2. Fig. 2 is an elevation ofsame with part in section. Fig. 3 is a plan view of the vat and groovedguiding-wheels and upper portion of the apparatus removed, and Fig. Lisa perspective view of one of the bearing-disks.

A is the vat and contains within it a shaft Gr, carried in bearings orsupports 1, secured within the vat. This shaft is stationary and hasthreaded upon it a series of bearing-disks H, having oblique holes toreceive the shaft G and are furthermore provided with keyways to receivea longitudinal key or feather g of the shaft. In this manner the disks Hare all caused to assume similar positions and lie in parallel planesoblique to the shaft and at the same time to remain stationary. Journaled upon these bearing-disks H are a series of idler-wheels F,having grooved rimsf. The obliquity of the disks produces a stepconstruction, as shown in Fig. 3, and the projecting faces of thedisksact as side bearings to hold the wheels F in position while freelyrevolving under the driving action of the traveling yarn. If desired,one of these wheels F may be omitted and adivision-plate Aintroduced todivide the vat into two compartments, as shown in Fig. 3, and whichwould enable the yarn to be subjected to two fluids while in the custodyof the machine.

Journaled in upper housings at C C is a cylindrical roller B, of metal,which is driven by gearing D E- and band-wheel E. This roller is locatedimmediately above the shaft G and wheels F and so as to preferably bewhollyclear of the fluid in the vat A. The yarn passes alternately aboutthe cylindrical roller B and the wheels F, being advanced by theobliquity of the wheels, as will be readily understood. As shown, theobliquity of the wheels is such that two webs of yarn may be fed throughthe machine at the same time without tangling, and by varying theobliquity or the diameters of both of the wheels the yarn may be causedto pass over every wheel or every third wheel, as designed. The groovesf of the wheels F are preferably formed with flat bottoms, and this,with the roller B, causes the threads of the yarn web to lie flat or inribbon form, so as to expose each thread to the fullest extent both tothe liquid and squeezing process.

Arranged above the roller B is a tubular rubber roller J, which isflexible throughout and adapts itself readily to the requirements,passing over knots or lumps in the yarn at any point without removingthe pressure upon other portions of the yarn. Pressure is applied tothis tubular roller by two revolving rollers K L, arranged above it andrespectively upon opposite sides of a vertical plane through its axialline. The roller K is journaled in fixed bearings in the frame of themachine, while the roller L is journaled in hinged frames M, and therebyadjusted to or from the rollers J and B under the action of ascrew-shaftN and hand-wheel nuts a. Any other means of adjustment of the roller Lmay be employed in lieu of that shown. By the adjustment of roller L anydegree of pressure desired may be put upon the tubular rubber roller J.To assist the roller J to revolve with a speed commensurate with theroller B, I cause the rollers K L to rotate also at the same surfacespeed as the roller J, and this I accomplish by providing the saidrollers K L with pinions O, which are geared to a spurgear P on theshaft of the roller B by intermediate gears Q. Any other form of gearingmay be employed, if so preferred.

I have shown my apparatus in the form I have found excellently adaptedfor commercial use, and while I prefer the construction shown' I do notconfine myself .to the details, as they may be modified withoutdeparting from the spirit of the invention.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is
